Because the impact of unmanaged interactive sessions can be significant, the concept of login nodes in Bright Cluster Manager was introduced in Part 1 of this series. Although login nodes address many considerations relating to interactive use, they are designed to do so in a limited way. For example, in Part 1, the following consideration was outlined (emphasis added here):
Whether it’s force of habit, or from actual need, users of HPC environments crave interactivity. Because the impact of unmanaged interactive sessions can be significant, there exists the potential for concern. Is it possible to meet users’ need for interactivity while managing the potential for impact? In this first part of a two-part series on managing interactive impact, attention focuses on the introduction of login nodes to a cluster managed by Bright Cluster Manager. The second part in this series will focus on use of workload managers as a complementary means for managing the interactive impact on the compute nodes of a cluster.
The Bright Cluster Manager CMGUI makes tasks intuitively easy. This article shows how you can view and control workload manager jobs using the Bright CMGUI. I am using an OGS (SGE) job to provide examples, but Bright works the same way with all Bright's supported workload managers: PBS Professional, Slurm, Univa Grid Engine, LSF, openlava, TORQUE/Moab, TORQUE/Maui.
Bright Cluster Manager takes away the complexity of managing Linux clusters. One such example is how using Bright's intuitve CMGUI you can easily provide read-only access to the cluster. This article shows how to create an x509 certificate based on the read-only authorization profile in five fast and easy steps.
